Abstract
Pirolisis merupakan salah satu metode untuk mengubah limbah plastik menjadi bahan bakar. Temperatur pada proses pirolisis merupakan salah satu faktor yang mempengaruhi proses pirolisis. Pada laporan ini telah dirancang sistem pengenadlian temperatur pada combustion chamber yang berfungsi untuk mengatur temperatur tetap terjaga. Set point temperatur yang digunakan adalah 200℃ dan 250℃. Sampah plastik yang digunakan adalah sampah plastik PE. Dan lama proses pembakaran pirolisis adalah 30 menit. Perancangan sistem pengendalian temperatur diawali dengan menggunakan sensor termokopel tipe K yang dihubungkan dengan mikrokontroller jenis ARM STM32 dan Motor Operated Valve (MOV) sebagai aktuator. Termokopel tipe K bertugas mengukur temperatur yang ada di dalam combustion chamber dan MOV bertugas mengatur laju alir gas untuk mengendalikan nyala api pada kompor. Sistem pengendalian yang digunakan adalah mode kontrol P (Proporsional). Nilai akurasi sensor sebesar 99.03% dan histerisis sebesar 1.81%. Pada set point temperatur 200℃ dengan nilai Kp sebesar 1,53, terjadi overshoot sebesar 209℃ atau memiliki selisih sebesar 9℃. Rise time sebesar 6 menit dan time peak pada menit ke 7, dan settling time sebesar 11 menit.

Pyrolysis is one method to convert plastic waste into fuel. The temperature in the pyrolysis process is one of the factors that influence the pyrolysis process. This report has designed a system for temperature recognition in the combustion chamber which serves to regulate the temperature maintained. The set point temperature used are 200 ℃ and 250℃. The plastic waste used is PE plastic waste. And the duration of the pyrolysis combustion process is 30 minutes. The design of the temperature control system begins with the use of a type K thermocouple sensor that is connected to an ARM STM32 microcontroller and Motor Operated Valve (MOV) as an actuator. The type K thermocouple is in charge of measuring the temperature inside the combustion chamber and the MOV is in charge of regulating the gas flow rate to control the flame on the stove. The control system used is P (proportional) control mode. Sensor accuracy value is 99.03% and hysteresis is 1.81%. At a set point temperature of 200 ℃ with a Kp value of 1,53, overshoot occurs at 209 ℃ or has a difference of 9 ℃. Rise time is 6 minutes and peak time is 7 minutes, and the settling time is 11 minutes.
